To assess daily or on-demand ease of use, and efficacy of the home use of the Viberect device by men with mild to moderate and no erectile dysfunction [ Time Frame: 4 weeks after initiation of intervention ] [ Designated as safety issue: No ]

After obtaining informed consent, the subjects will be instructed in the use of the Viberect device, and will be asked to perform vibratory stimulation of the penis in the privacy of their home, while focused on sexual/erotic thoughts for approximately 7-10 minutes (depending on erectile response) for 3 times a week, one day apart, throughout the four week period. Men can perform the stimulation once daily, as long as each session is more than 24 hours apart. Men will record device use and intercourse attempts after device use in a diary. They will fill out several validated questionnaires on week 4: Erection Hardness Scale (EHS), EDITS (Erectile Dysfunction Inventory of Treatment Satisfaction), TSS questionnaire

Descriptive Information

Brief Title ICMJE

Assessment of Penile Vibratory Stimulation Using the Viberect in Men With Mild-Moderate and No Erectile Dysfunction

Official Title ICMJE

Clinical and Physiological Assessment of Noninvasive Penile Afferent Vibratory Stimulation of Both Surfaces of the Penis Using the Viberect® Device in Men With Mild to Moderate and No Erectile Dysfunction.

Brief Summary

The primary purpose of this study is to assess the safety, acceptability, and satisfaction of penile vibratory stimulation. The secondary purpose is to demonstrate subjective physiological response (erection, rigidity, orgasm) after four weeks of frequent device use and the satisfaction of penile erection and sexual intercourse with partner.

Detailed Description

Erectile dysfunction (ED) is the inability to develop and maintain an erection for satisfactory sexual intercourse or activity. ED is a highly prevalent medical condition often associated with multiple causes. It is estimated that more than 50 million American men suffer from mild/moderate to severe erectile dysfunction. Roughly 50% of men in their 50's, 60% of men in their 60's, and 70% of men in their 70's suffer from ED. The economic impact of ED is in the billions of dollars. More than 5 billion dollars a year are spent on the three pro-erectile medications currently in the market.

Penile vibratory stimulation mimics rapid and repetitive manual/hand stimulation of the penis, which is a natural aspect of human sexual behavior. For more than a century, tens of millions of women use vibratory devices on daily/regular basis for purpose of sexual pleasure/orgasm. Vibratory stimulation of genitalia is considered safe by the medical community with important benefits, such as treatment of orgasmic dysfunction, stress urinary incontinence, ejaculation, and erection. No significant physical or emotional side-effects have been reported in the medical literature, or the popular media. A recent epidemiological study of the use of vibrators by American women and men has shown no complaints, and generally high satisfaction and improvement in sexual response.

Penile erection is controlled by spinal autonomic centers, the activity of which is dependent on input from supraspinal centers and genitalia. From a neurophysiological viewpoint, scientists believe that penile erection is a culmination of multiple successful nerve reflexes that initiate a vascular event. Simultaneous vibratory stimulation of both surfaces of the penis at high frequency (70-110 Hz) for 7-10 minutes can lead to reflexogenic gradual filling of the penis (minutes) with arterial blood by activating the pudendo-cavernosal reflex. Additional physiological effects include progressive rhythmic contraction of the perineal muscles via activation of bulbocavernosus reflex, which helps in strengthening rigidity of erection. This will prepare the user for successful sexual intercourse. Subsequent orgasm and ejaculation can be very strong and amplified due to stronger contraction of the bulbospongiosus muscle and activation of higher ejaculatory centers.

The purpose of this multicenter study is to assess daily or on-demand ease of use, safety, satisfaction, and efficacy of the home use of the Viberect device (FDA cleared) by men with mild to moderate and no erectile dysfunction.

Men will be asked to perform vibratory stimulation of the penis in the privacy of their home, while focused on sexual/erotic thoughts for approximately 7-10 minutes (depending on erectile response) for 3 times a week, one day apart, throughout the four week period. Men can perform the stimulation once daily, as long as each session is more than 24 hours apart.

Men will record device use and intercourse attempts after device use in a diary.

Study Arm (s)

Experimental: men with mild-mod. erectile dysfunction

Expected duration of subject participation: 4 weeks Initial visit: to perform history and physical, to discuss the clinical study and obtain informed consent. Study subjects will fill out the International Index of erectile Function (IIEF) questionnaire, the Erection hardness Score (EHS), the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire and the Treatment Satisfaction Survey (TSS) to fill out after 4 weeks, and receive instructions on the use of the Viberect device, including the User manual.

Follow up visit four weeks later: To return the Viberect device and collect the completed forms. The patient will have a penile examination to document any sores, lesions, or irritation.
